Abstract
BACKGROUND Weight-based stigmatization is frequent among overweight and obese people. AIM: To determine the association between weight-based stigmatization, psychological stress, cortisol, negative emotions, and eating behavior in a sample of middle-aged women. MATERIAL AND METHODS Eighty-two women aged 45 ± 8 years, 55% with overweight or obesity, were randomly allocated to watch a video called "Stigma: the human cost of obesity" or a control video about planet earth. The effect of watching either video on calorie consumption, psychological stress and cortisol reactivity was assessed. Cortisol was measured on four salivary samples. Psychological stress and negative emotions were self-reported. RESULTS Among women who watched the stigmatizing video, there was a direct association between psychological stress and calorie intake, but negative emotions did not mediate this association. Moreover, psychological stress moderated the association between watching the stigmatizing video and the cortisol output (β = 0.32; p = 0.005). CONCLUSIONS Women with high psychological stress have a greater intake of calories. After watching the stigmatizing video, a greater psychological stress is associated with greater cortisol output.

Health Consequences of Weight Stigma: Implications for Obesity Prevention and Treatment.

Abstract
Despite decades of research documenting consistent stigma and discrimination against individuals with obesity, weight stigma is rarely considered in obesity prevention and treatment efforts. In recent years, evidence has examined weight stigmatization as a unique contributor to negative health outcomes and behaviors that can promote and exacerbate obesity. This review summarizes findings from published studies within the past 4 years examining the relationship between weight stigma and maladaptive eating behaviors (binge eating and increased food consumption), physical activity, weight status (weight gain and loss and development of obesity), and physiological stress responses. Research evaluating the effects of weight stigma present in obesity-related public health campaigns is also highlighted. Evidence collectively demonstrates negative implications of stigmatization for weight-related health correlates and behaviors and suggests that addressing weight stigma in obesity prevention and treatment is warranted. Key questions for future research to further delineate the health effects of weight stigmatization are summarized.
